This was a product idea/concept for a contest. It was never an actual product. The contest occurs every year to generate new ideas that may or may not actually result in real products. Unfortunately, some "data miners" find such things and spread them around the internet and they get treated like real products. This is one of the reasons you have to be very careful about what you read or see on the internet.

It was actually more than a concept, at least one company spent a small fortune trying to develop the device. I acutally had the opportunity to test it a few years ago - at that time, it was about the size of a quart of milk, and was eventually abandoned because of technical problems. The concept, however, is legitimate.
